Letters Patent No. 106,237, dated August 9, 1870.

. IMPRQVEMENTJN cocks.

` The Schedule referred to inv these Letters Eatent. and making part of the same provemeu ts. i

It isin construct-ion of the valve A' that my im-V provements consist particularly, the faucet consisting of the ordinary casting B, with a/quick-threaded stein-C, the valve shutting :down upon the valveseat D.

` 'Ihe construction of this valve is as follows:

The packing consistsof a rubber plug or cushion, E, cylindrical iii form, and `having a Hat face at the xixcttom of suicient width to completely cover the valve-seat orifice F.

This rubber v.piece screws into the middle piece'Grof the valve, which has a screw-socket, H, cui: int-o its lower portion for the reception of the plug.

This piece G has at the top another screw-socket,

into which screws a cap, I, which connects the stem of the -fancet with the valve by this means, the cap I having a hole through it, through which the stem C passes, the latter having a head, K, on its lower end.

Figs. II and III show partial sectional vewsofv these parts. p

` In this manner I forma simple and 'easilyeconstructed valve, perfect iu its operation, and easilytaken o or adjusted, as it is only necessary to unscrew the cap I or to screw it in in order to detach or attach the stem and valve.

Now having described my invent-ion, lll/'hat I claim as new, and desire to secureby Letters Patent, is-

'lhe combination of the stem C with thc head K,

capV I, center piece G with screwfsockets and rubber plug E, all` arranged and constructed as shown, and for the purpose `set forth. I
